. Application tiled March 8, 1902.

To @ZZ whom/t may concern/.-

Be it known that'Ll OLIvnR OROMWELL JONES, of the United States Navy, a citizen of the United States, and a resident of Philadelphia, in' the county of Philadelphia and form may be employed to drive the pump.

This specification is an exact description'of one form of my invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification,

. in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a horizontal section of the invention on the line 1 1 of Fig. 3. Fig. 2 is a section on the line 2 2 of Fig. 3. Fig. 3is an elevational view from the line 3 3 of Fig. 2, and Fig. 4 is a cross-section on the line 4 4 of Fig. 2.

Referring to Fig. 1, 10 indicates the pumpcylinder, and 11-the engine-cylinder. The

engine-cylinder is fitted with a rotary pistony 12, abutments 15, and steam-controlling'de- Vices 16, all as described in my copen'ding application above referred to. As Fig. 1 illustrates, the engine and pump are coupled directly together, the cylinders being divided by a Wall 17. This arrangement of the rotary engine and pump is according to my preference; but obviously an engine of any sort might be used to drive the pump.

As best shown in Figs. 3 and 4, the pumpcylinder 10 has offset portions 1S at each side, and in these pairs of odsets pairs of abutments 19 are arranged to work. These abutments 19 are carriedon trunnion-shafts 20, which are mounted in the sides of the cylinder.

2l indicates the pump-piston, which has a packing-strip 22 at its outer end, this packing-strip being pressed outward by. a spring 23, so as to make water-tight connection with the pump-cylinder and with the abutments.

Serial No. 97,252. (No model.)

AThe piston is arranged to turn in the cylinder and coacts with the abutments, as will be fully'described hereinafter, the abutments rocking on their trunnion-shafts to allow the Vpiston to pass them and afterward falling back upon the piston and its hub 24, as the drawings show.

25 indicates the inlet-pipe, which passes into the cylinder 10, preferably at the bottom, and 26 indicates the outlet or discharge pipe, which passes from t-he center thereof. Mounted in the cylinder at the sideof the piston is a transverse wall 27, which has circular edges engaging the sides of the cylinder. This wall 27 is cut away-at ltwo points, (indicated at 28 and 29,) such points lying adjacent to and on opposite sides of the piston, as best shownin Fig. 4. The opening 28 does not extend to the periphery of the wall and is therefore an inclosed opening, and the opening 29 extends outward to the periphery of the wall, as Fig. 4 shows. This wall 27 fis fastened rigidly to or formed integral with the hub 24 of the piston, so as to turn therewith. This fastening may be eected in any Y desired manner; but it is preferred to cast or otherwise form integral the parts 21, 24, and 27. Formed on the right-hand side of the wall (see Fig. 2) is a casing.30, which communicates with the said opening 28 in the wall, vthis casing 30 lying -between the wall and the right-hand head of the cylinder and having a centrally-disposed opening 31 in exact registry with the discharge-pipe 26.

32 indicates packing of any suitable form placed at the end of the outlet 30, so as to prevent leakage at this point, and 33 indicates packing extending around the periphery of the wall 27 from one side of the opening 19 to the other.

The hub 24 has at its left-hand or inner end a central extension 34, which is set in a bearing 35, formed in the central wall 17, and this extension 34 has lnortised engagement with a corresponding extension 36 from the hub of the engine-piston. This connects the two pistons rigidly together, so that the latter may be turned from the former. 37 indicates a tie-rod which is passedv through the hub of the piston 21 and the extension 34 and screwed into the hub of the engine-piston 12. At the right-hand end of the rod 37 IOO a nut 3S is placed, and this nut presses a spring 39 against the wall 27, whereby the parts 21, 27, 30, and 12 are drawn forcibly against the central wall 17, so as to prevent leakage. The engine-piston is carefully packed, as illustrated and described in my before-referred-to copending application, and the pump-piston 2l may also be packed as desired, so as to keep it water-tight. The abutments 15 of the engine are actuated by steam-pressure, so as to yieldingly maintain their proper positions, and the pump-abutments 19 are connected with the engine-abutments, so that the pump-abutments also will be held yieldingly in the proper position.

This connection is effected by tenoning to-` gether the trunniou-shafts 20 of the pumpabutments with the trunnion-shafts 40 of the piston-abutments, as indicated at 4l. The construction is given greaterstrengt-h by means of studs 42, fastened to or formed integral with caps 43, which are held on the outer head of the engine-cylinder and project into the hollow trunniou-shafts 40. The trunnion-shafts 20 are also hollow and have placed therein cylindrical blocks 44, which are fastened rigidly to rods 45. These rods 45 project through the adjacent ends of the trunnion-shafts 2O and 40 and are screwed into the studs 42. These parts 42, 45, and 44 being rigid and carrying loosely the trunnion-shafts allow the abutments to swing freely, but at the same time they sustain them firmly in the proper adjustment, and even should the left-hand head of the pumpcylinder be removed the pump-abutments will not fall from place.

The operation of l[he pump is as follows: As the steam-pressure is applied to the engine-abutments it is transmitted to the pumpabutments by the abutment-connecting devices, and when the steam is admitted into the engine-cylinder the pump-piston is driven around in the pump-cylinder. The movement of the piston carries with it the wall 27 and case 30, and the liquid is sucked iu through the pipe 25, it passing into the space between the wall 27 and the adjacent head ofthe pumpcylinder. The water is drawn from here by the sucking action of the pump through the opening 29 in the wall 27 and lies in the cylinder back of the piston, assumingthat the piston be moving in the direction of the arrow indicated in Fig. 4. Simultaneously the water is being forced out through the opening 2S, case 30, and discharge 31. Assuming the parts to be in the position shown in Fig. 4, the piston moving to the left will coact with the lower left-hand abutment 19, and the water will thus be forced through the opening 28. As the movement ot' the piston continues this discharge action will be continued until the piston strikes the lower left-hand abutment and passes the same, whereupon the piston in moving around toward the right-hand side acts with the upper right-hand abutment 19 in the same manner as that above described. Meanwhile the sucking action ofthe pump goes on continuously, thus keeping the cylinder at all times full of the water ready for the action of the piston in forcing it out through the discharge. The pump may be readily reversed, so as to drive it in either direction and so as to convert the discharge 26 into the inlet and the inlet 25 into the discharge. The reversal of the engine of course is necessary to the reversal of the pump, and, as may be understood by reference to my copending application, the reversal of the engine will also reverse the steam-pressure on the engine-abutments, and these in turn will reverse the pump-abutments. As Iexplained,

itis desirable to drive the pump with the special form of engine shown; but obviously any motive power could 'ne applied for this purpose. lVhen using other power for the pump, the pump-abutments may be caused to assume their proper positions by applying to them the water-pressure from the discharge of the pump the same as the steam-pressure is utilized in the engine, or, if desired, any other means may be used to yieldingly hold the abutments. Also when working the pump without connecting the abutments with those of the rotary engine the abutments should be properly packed against the walls of the offsets 18, so as to prevent the water from being forced back of the abutments, which would disturb the equilibrium of the pressure on the abutments, and therefore interfere with the effective operation of the pump. These and various other changes in the minor features of my invention may be resorted to at any time without departing from the spirit thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A pump, comprising a pump-cylinder with inlet and outlet orifices, a rotary piston, a swinging abutment mounted in the cylinder, a wall arranged at one side of the piston and turning therewith, said wall being spaced from the adjacent head of the cylinder and having orifices at the respective sides of the piston, and a chamber attached to the wall and communicating with one of the openings in the wall and also communicating with the discharge or outlet orice.
